That’s the only test that counts. It’s not how hard you work, it’s what happens if you stop. If quitting means real hardship for you or your family, you have a job. If you keep at it even though you could spend the rest of your life skipping rocks at your house by the lake, you have a hobby.
I’ve got nothing against hobbies. The Weekly Sift is a hobby. One way to describe the Marxist vision of Utopia is that we’d all be hobbyists, and the world’s work would get done by people who just wanted the satisfaction of doing it. (That vision even works sometimes: Wikipedia, open source software, and so on.)~ Doug Muder from, http://weeklysift.com/2012/04/16/rich-people-dont-have-jobs/
